Optional Tilt Backhoe Control Console

An optional tilting backhoe control console is available so the operator can adjust the controls fore or aft to suit his individual level. This option is a Case exclusive. Benefits include:

□ Improved comfort.

□ Improved backhoe control.

□ Improved productivity.

Note: Only available for the Case three-lever controls with foot swings.

Relocated Stabilizer Levers

Both stabilizer levers are now located on the left side of the backhoe control console. The operator can lower or raise both stabilizers with one hand while using the other to perform other functions. This reduces the time required to reposition the unit.

Backhoe Control-Lever Conversion

The time to change from Case three-lever controls with foot swings to dual-lever controls has been reduced from 8 hours to 2 hours, a 400-percent improvement.

Sealed Pins and Bushings

Like the loader, the backhoe pivot-point lubrication interval has improved 500 percent, from every 10 hours to every 50 hours, due to sealed pins and bushings in most of the pivot points. Benefits include:

□ Less service time.

□ Reduced operating cost.

□ Longer pin and bushing life.

Improved Pivot-Point Pin Retention

Most of the 580K backhoe pivot points are attached on one side by a keeper pin inserted into a pivot pin, retained by a bushing, and on the other side by a bolt and flat washer. Benefits are:
